UNITED sTATEs PATENT f oEEIoE.

To all whom, t may concern:

Be it known that I, FRANK ONEILL, a citizen of the United States, residing at Detroit, in the county of Wayne and'State of Michigan, have invented certain new and useful Im-.

provements in Bottle-Finishing -Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to apparatus for finishing bottles, and has particular reference to an adaptation for such use of the apparatus shown and described 4in my application, Serial No. 229,473, filed October 21, 1904. The invention as embodied in that application is designed primarily for finishing tumblers and similar objects, and while the underlying principles thereof are available for finishing bottles as well as tumblers, yet the specific embodiment of the operatingfparts is necessarily different for the two uses, and hence the primary object of the present invention is to so change the mechanism of the former application, without disturbing the underlying principles thereof, as to adapt it for bottle-nishing use.

A further object is to provide bottle-neckfinishing devices of improved construction and to provide for moving a series of such devices into operative position successively, thus proved snap or holder for sustaining bottlesl while being finished.

A further object is to provide for resisting undue pressure of the formers on the reheated and softened glass by admitting air under pressure into the bottle during the finishing operation.

In the accompanying drawings, Figure 1 is a vertical sectional view of the apparatus, the left-hand side of the figure being taken in the plane of the finishing mechanism and illustrating the positions of the several parts during the finishing operation. Fig. 2 is an enlarged sectional view of a portion of. one of the finishing devices. Fig. 3 is a side elevation of the opposite side of the upper portion of the machine from that shown in Fig. l. Fig. 4 is an edge View, and Fig. 5 a vertical sectional View, of said upper portion. Fig. v6

-is a diagrammatic plan view. Fig. 7 is a sectional view of the reheating-hood andf a portion of the carrier, also one of the bottle-holders. Fig. 8 is a detail view of the bottle-hold- Speccaton of Letters Patent. Application filed July 13, 19-05. Serial No.. 269,538.

ing snap. Fig. 9 is a similar View of the spring-'latch device for actuating the carrier of the finishing mechanism.

Referring to the drawings, 2 designates the base, and 3 the central uprigh t,\of the machineframe,` and rising from the latter is hollow post 4. Secured to the post is bearing 5, and rotatable thereon is the horizontal ware carrier or table 6. Above the table is a circular series of bottle-holders or snaps, each of which is mounted on a vertically-movable shaft 14, and beneath and rotatable with the table is mechanism for rotating the shafts at either low or high speed, also mechanism for raising and lowering the same. Each of these under mechanisms consists of a frame 15, provided with a vertical bearing 15', and journaled in this bearing is tubular hub 16, carrying the large horizontal gear-wheel 17 and the relatively small gear 18. J ournaled in frame 15 is a horizontal shaft 19, and rotatable on the outer portion of this shaft is gear 20, meshing with gear 18, and a gear 2l, meshing with gear 17. A double clutch device 22 is arranged between gears 20 and 21, which is adapted to engage the' same interchangeably for driving spindle 14 at either low or high speed, said device being operated by lever 23. The latter carries roller 24, which rides on the under-face of cam-ring 25, being held in engagement therewith by spring 26, all as in my applicationy above referred to. The inner end of shaft 19 is geared to wheel 27, journaled on post 4, said gear being driven by the short vertical shaft 28, the latter being geared to the main horizontal drive-shaft 29.

For moving shaft 14 vertically for the pur- `being supported by the circular vertical eX- tension 2 of the frame.

The bottle-holder or snap at the upper end of shaft 14 consists of a head or base 36 upon which the bottle-"rests, and hinged thereto at their lower ends are the bottle-clamping segments 37. `Linkedl to each of these segments is a weighted lever-37', fulcrumed to arm 36 of base 36.l When shaft 14 is being driven IOC IIO

by the slow gear, as it is throughout the revolution of the carrier excepting when at the finishing position, the centrifugal force is not sufficient to raise the weighted arms and cause segments 37 to clamp the bottle. This clamping hold is necessary only during the finishing operation, at which time shaft 14 is rotated by the high-speed gears 18 and 21 when the speed attained is sufiicient to raise the weighted arms and cause the segment-plates 37 to tightly clamp the bottle, causing the latter to rotate therewith in direction opposite to the finishing mechanism, as will pre. ently appear.

The finishing mechanism is supported by a frame or bracket 38, extending laterall y from post 4. Projecting from the outer lower portion of this frame is a spindle 39, and rotatable thereon is a wheel-like carrier 40. Each of the four radial arms of this carrier supports a finishing mechanism which are turned downward successively into operative position in line with the bottle-holders, carriers 6 and 40 being advanced intermittently at the same time, so that a fresh finishing mechanism is presented as each bottle is moved to the finishing position.

For imparting a quarter-turn to carrier 40 an arm 41 is adapted to turn on'spindle 39 and carries a beveled spring-latch 42, which successively engages notches 40 in the hub of carrier 40, the latch being arranged to move backward freely, but to interlock with one of said notches when moving forward. For oscillating arm 41 a link 43 extends to crank 44 on one end of the horizontal rock-shaft 45, journaled in frame 38. At the opposite end of the rock-shaft is the short arm 46, connected by a link 46 with vertical rod 47, the latter being slidable in guides on frame 38 and held normally depressed by coiled spring 47.

For operating the several parts of the finishing mechanism a tubular shaft 48 and a solid shaft 49 are extended upward through post 4, said shafts, respectively, being driven at their lower ends from shaft 28 by gearing 48 and 49. Secured to the upper end of tubular shaft 48 is the disk-like wheel 50, having on its lower face the depending cam-like projection 51 and on its top face a' corresponding projection 52. Spring 47 holds rod 47 raised, with roller 47" at the upper end thereof pressed upward against the under face of disk 50. When, however, the latter is so rotated as to move projection 51 over the roller and depress rod 47, the downward movement thereof operates to rock shaft 45 and to move the parts connected thereto into the position indicated in dotted lines in Figs. 1 and 3, thus advancing carrier 40 a quarter-turn and placing a'fresh finishing mechanism in operative position. As soon as projection 51 passes rod 47 the latter is raised by the spring and the parts operated by it are restored to the fullline positions indicated in Fig. 1 and in position to impart the next quarter-turn to the finishing-mechanism carrier.

Each of the four fi nishing mechanisms consists of a stem o1' shaft 53, rotatably secured in carrier 40 and at its outer end carrying a plug 54 for the interior of the bottle-neck. Also carried by stem 53 is a. head 55, and hinged thereto are the radially-arranged exterior neck-formers 56, four being here shown. Links 57 connect these hinged formers with head 58, slidable on the inner portion of stein 53, and a spring operating on the stem bctween heads 55 and 58 holds the latter normally pressed inward or toward carrier 46, with formers 56 open. Plug 54 and formers 56 may be variously shaped as required for imparting the required shape to the interior and exterior of the bottle-neck.

Secured to the inner extremity of each stem 53 is a friction-wheel 59, and as each of the finishing mechanisms is turned downward into operative position this wheel is placed in engagement with the constantly and rapidly rotating wheel 60, carried by the lower end of vertical shaft 61, journaled in the outer portion of frame 38. This shaft is driven by a belt 62, extending from a pulley carried by the upper extremity of shaft 49.

Slidable on one side of frame 38 is the bar 63, having at its lower end a roller 63', which operates upon the depression of the bar to depress head 58 of the operative finishing mechanism, and thereby close and hold closed formers 56 around the bottle-neck being operated upon. Bar 63 is raised and lowered by means of a lever 64, fulcrumed to frame 38. The outer end of this lever is forked, as indicated at 64, with shaft 6l extending' therethrough. One fork of the level is connected by a link to lateral extension 63 of bar 63, and the other fork is similarly connected to a collar 65, slidable on arod 66. This rod is movable vertically in guides projecting from frame 38 and is held normally raised by the spring 67, but is adapted to be depressed by the downward movement of the lever` the cushioningspring 67 being placed on the rod between collar 65 and stop 66', fixed to the rod. At the lower end of the rod is an upwardly-recessed head 66 for engaging the plug` 54 of the upturned finishing device, thereby firmly holding the entire finishing mechanism and maintaining the active downwardly-disposed device in proper alinement. Bar 63 and rod 66, with lever 64, are normally in raised position. For depressing the same the rear end of the lever is connected by a link 64 to a vertical rod 68, similar to rod 47, but held normally depressed (with the outer portion of the lever raised) by a spring 68. At the upper end of said rod is a roller 68, which overhangs disk 50 and is adapted to be raised at the proper interval by projection 52 passing therebeneath.

Ring 35 is of concentric forni, except for IOO ISO

bulge 35', which in length is a little shorter than the distance between the lever-tilting rollers 34, the arrangement being such that when the ring is oscillated this bulge is -moved -forward and backward across the radial line of the finishing mechanism. For advancing carrier 6 step by step an oscillatingarm 69 is employed, which may be operatedin any suitable manner. Asring 35 requires an os- `cillating movement similar to arm69, I connect said parts by providing the ring with a projecting arm which isl connected by rod 70' with a depending extension 69 of the outer end of arm 69. Arm 69 having advanced table 6 in the direction indicated by the left-hand arrow in Fig. 6, said arm reaches the limit of its movement, which is indicated by the fullline position in saidifigure. Then as the arm advances to the position'indicated in dotted line for securing a hold* for the next advancing movement it moves with itv ring 35, causing bulge 35' to throw outward lever-'roller 34 of the mechanism at the Jnishing-station C, thereby raising the bottle-holder and placing the neck thereof between formers 56 and with plug 54 depending thereinto, this position being maintained until bulge 35 has passed backward over roller 34 and into the position indicated in dotted lines in Fig. 6, when the roller is free to move inward, thereby lowering the bottle-holder. At this juncture arm 69 has reached the limit of its movement (indicated in dotted lines in the same figure) and is ready to advance carrier 6 another step, and as the carrier thus advances all of the under mechanisms conn-ected thereto move with it, including levers 32 and rollers 34. Ring 35 is oscillated at the same time and in the same direction, sothat bulge 35' remains between two of rollers 34'and is moved from the dotted to the solid line position (seen in Fig. 6) and in readiness to operate roller 34 of the mechanism then at finishing position C upon the next backward oscillation of ring35;

In operation the unfinished bottles maybe placed in `the several holders or snaps on the carrier by means of the transfer'mechanism shown and described-in myformer application or in any other convenient manner.

The bottles are then advanced step by step( beneath the bottomless reheating hood or chamber 7l, in'to which their necks or upper portions project, as shownin Fig. 7. Thusl only that portion of each bottle is reheated andv softened that requires refinishing, the lower portion being unaffected, so that it is not injured or distorted by the gripping pressure of the snap-sections when held bythe latter during the period of rotation at high speed at the finishing position.l As each bottle 'dle.39.

bulge 25of ring 25, and this high speed causes the snap to close and tightly grip the bottle, as above described. r[he operation of the -machine is so timed that a fresh finishing rounding the plug 54; At this instant lever`- 64 is so operated as to cause rod 66 to engage and hold the finishing mechanism properly centered, and at the same timel bar 63 is depressed, causing roller 63 to depress head 58 and close formers 56 around the bottle-neck. Before bulge 35 completes its backward traverse of roller 34 bar 63 is raised and the formers 56 permitted to swing outward, so that when roll-er 34 `drops from engagement with the bulge 35' the, bottle-neck is released and free; to move downward with the holder.

During the finishing operation the several parts rotate very rapidly, and the finishing is accomplished almost instantly, the formers 56 being closed and again opened while the bottle during the time bulge 35 is moving backward .SAA

past roller 34. Then while a fresh bottle is l being. moved linto the finishing position C the mechanism above described is operating to turn a fresh forming mechanism into operative position.

Projecting from crank 44 is an arm 72,`

which carries a swab 7 2', which may be'soaked with a solution of oil and charcoal and which is so positioned that as arm 44 moves the mechanism forward for a fresh vhold on the finishing-mechanism carrier, as shown in full ICO lines in Fig. 1, the swabis moved inward under pressure to the bottle during the finishing operation by forming a duct 54 through plug 54, with which registers duct 7 3 of stem 53, the latter registering with passage 74, extending through carrier 40 to spindle 39 and adapted when in downturned or operative position to register with passage 75 of spin- Air under pressure may be supplied from a suitable source through the hose connection 76.' Thus the shape of thel bottle is preserved, the internal air-pressure counteracting any tendencyon the part of the inwardly-pressing external formers to distort intermittently-movable series of bottle-holdthe softened glass. While I consider this a desirable feature, the operation of the apparatus is not dependent thereon and the same may be omitted.
